Product details
Product Introduction/ Product introduction
The monitoring of drinking water sources and surface water monitoring system - [KNF-400A] adopts a sensor electrode monitoring scheme, which does not require consumables and maintenance, and has low cost. The main monitoring parameters include pH, turbidity, temperature, conductivity, ammonia nitrogen, COD and other indicators that can be selected and uploaded to the Kenaf water quality detection platform through GPRS, and synchronously published on the LED large screen.
KNF-400A is a water quality online monitoring system developed based on the relevant requirements of the "Sanitary Standards for Drinking Water" to provide basis and support for strengthening the management of drinking water safety. It mainly targets water quality such as pH, turbidity, temperature, conductivity, water level, ammonia nitrogen, etc, COD， The implementation of online and early warning for water quality factors such as turbidity can expand other parameters. The product adopts a modular design, which is easy to install and maintain, suitable for monitoring needs of single points and large-scale distribution.
At the same time, based on its research and development, production, and operation experience in water quality online terminal monitoring equipment, data collection and transmission, and environmental monitoring management systems, Shenzhen Kenafu Technology Company has a long-term, stable, and effective solution for monitoring the characteristics of drinking water. This system can achieve digital management of the entire process of monitoring and analysis, data collection and transmission, equipment control, monitoring and early warning of drinking water, promoting the informatization and modernization of drinking water management, and comprehensively improving the management level.
Application scope/ Scope of application
1. Online monitoring and early warning of lake water quality
2. Monitoring of municipal water supply and self built facility water supply
3. Real time monitoring and early warning of rivers and surface water observation points
4. Online monitoring of water quality for terminal water and box type secondary water supply
5. Water quality monitoring of rivers, lakes, hospitals, swimming pools, and other water supplies
6、Fish ponds for aquaculture and lobster farming
System Schematic/ Schematic
The main monitoring items of this system include pH, turbidity, temperature, conductivity, water level, ammonia nitrogen and other water quality factors that can be extended to other parameters. The system sensors are easy to install, plug and play, and distributed in a networked manner. In addition to the basic four key water quality factors, users can customize and add other monitoring parameters and cooperate with the (fish method) biological toxicity prediction system to complete warning work.
Installation case/ Installation case
Installation location: Shanghai, installation time: 2021, operating status: good
